What are the Lagrange points and why is Aditya-L1 headed to one? | Explained

Some of the most amazing phenomena in nature, from electromagnetic radiation and infrared vision to subatomic particles and cosmic rays, are invisible, and we get to know them only through their various applications. This is true of Lagrange points as well – points in space between celestial bodies where a spacecraft stays more or less stationary, as if…

Clues to ancient Kosi superflood say it could happen again today

At Rajiv Sinha’s laboratory in IIT Kanpur lie soil, sand, and rocks drilled out from across thousands of metres under the Karnali, Ganga, and Kosi rivers. Each sample, called a “sedimentary core” is held in a container 7.6 cm wide; together, they create snapshots of the rivers’ ancient history. Every centimetre of these cores reveals…

Antimatter observed to be falling down under influence of gravity

This handout illustration released by U.S. National Science Foundation on September 27, 2023, shows an anti-matter gravity experiment ALPHA-g at an undisclosed location. For the first time, scientists have observed antimatter particles — the mysteriously absent twins of the visible matter all around us — falling downwards due to the effect of gravity, Europe’s physics…
